Cretoxyrhinidae Glückman, 1958

Key morphological features: The Cretoxyrhinidae include some of the largest sharks of the Late Cretaceous. Their teeth resemble a modern mackerel shark. With teeth and a bite force capable of shearing bone, these predators opportunistically fed on both live prey and decaying carcases of larger animals. Dinosaur and mosasaur remains often have evidence of shark predation from the Western Interior Seaway.
